Dynamic programming solves a problem by combining solutions to overlapping subproblems, storing each result once so it is never recomputed. It applies when a problem has optimal substructure and overlapping subproblems.
Dynamic programming - Interview Concepts - ExtraBrain is part of ExtraBrain's local-first Mac workflow for live interviews, meetings, transcription, provider control, and responsible AI use.

ExtraBrain has 1 current public platform family, macOS, with support for 2 Mac CPU families: Apple Silicon and Intel.
ExtraBrain has 3 configurable data paths to review before sensitive work: local Parakeet transcription, local Gemma 4 where installed and compatible, and external providers you choose.
Top-down memoization caches recursive results; bottom-up tabulation fills a table iteratively.
Identify what parameters uniquely describe a subproblem and write the recurrence relating states.
Knapsack, longest common subsequence, edit distance, and grid path problems are frequent DP templates.
Use any live AI assistant only where interview, workplace, school, and platform rules allow it. Do not use generated answers to misrepresent your skills, experience, or authorship.
Short answers for people and crawlers comparing ExtraBrain with other live AI assistants.
Use it when a problem has optimal substructure and overlapping subproblems, so cached results avoid exponential recomputation.
Ask what minimal set of parameters describes a subproblem, then write a recurrence that builds larger states from smaller ones.
